Title: Asynchronous induction motor
Inventor: MORRILL GILES W
IPC: H02K1/08
Filed: 1992-11-27
Abstract: An asynchronous salient pole induction motor having a stator core with equally spaced teeth with inner ends having equal angular extent and defining a bore whereat a squirrel cage rotor is provided.  A main field winding includes serially connected coils embracing alternate stator teeth and connected across a single phase source of alternating current. An auxiliary field winding includes serially connected coils embracing consecutive teeth intermediate the teeth having the main winding coils thereon.  The auxiliary winding coils are phase displaced from the main winding coils.  Each of the teeth faces at their inner ends are shaped for increasing the air gaps on both sides of the center line longitudinal plane of each tooth thereby increasing the magnetic reluctance between each of the teeth and the rotor on both sides of the center line plane.  The laminations are first punched with circular shaped teeth inner ends and thereafter are punched to remove a cut-away portion from the teeth inner ends substantially near the tips of the teeth furthest away from the center line plane.

Title: Divisible sprocket wheel
Inventor: BOS ARNOLDUS J L
IPC: B65G23/06
Filed: 1993-03-19
Abstract: Title:  Divisible sprocket wheel ABSTRACT      Sprocket wheels for use in chain conveyors, for instance, are preferably of a divisible construction so as to enable each wheel to be removed from the shaft separately. Also, on the basis of considerations of hygiene, the outer side surface of such a wheel is preferably entirely flat when used in the food or beverage industry. Existing divisible wheels are either flat on the outside, but expensive, or not flat and cheap because they are made by injection molding. The synthetic sprocket wheel according to the invention is flat and cheap and comprises two wheel halves with axial planes abutting against each other, each wheel half consisting of two interconnected parts, made by means of injection molding, abutting against each other through a radial side face, with the cavities and ribs necessarily present for the injection molding process being located in the interior of the wheel half.

Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N21/647
Filed: 1993-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned.   Also, data of the second data stream are assigned to the signal points of each signal point group. A difference  in the transmission error rate between first  and second  data  streams  is  developed  by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into,  low and high,  frequency band components which are designated as a first and a second data stream respectively.     Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

Abstract: A pair of filtering membranes 52 are solidly bonded to a membrane-supporting plate 51 by fusibly bonding each of the filtering membranes 52 to the resin membrane-supporting plate 51. A main fusible domain 14a is formed along peripheral edges of each of the filtering membrane 52. In addition, a plurality of subordinate fusible domains 14b are intermittently formed in plural locations on one side or on both sides of the main fusible domain 14a. By virtue of the above structure, bonding strength is secured by the main fusible domain 14a, and yet, bonding strength is reinforced by locally provided subordinate fusible domains 14b. A channel is formed in the membrane-supporting plate 51 so that permeated liquid can swiftly flow through the filtering system. In addition, a plurality of projections 53 are formed an peripheral edges of a filtration membrane cartridge 5 facing inner surface of each gutter 12 formed inside of each slit plate 11 by way of causing respective projections 53 to slidably come into contact with the inner surface of the gutter 12. This in turn effectively minimizes frictional force between the filtration membrane cartridge 5 and the gutter 12 to facilitate operator to easily insert and remove the filtration membrane cartridge 5 into and from the gutter 12 of the slit plate 11.

Means is provided for rotating the locking arm between the retracted and the extended positions. Means is provided for positioning the lock assembly between a distal and proximal positions and an intermediate position disposed between the distal and proximal positions in which the look assembly engages the wheel.        Means is provided for controlling the position of the lock assembly between the distal and proximal positions in a programmed manner. The controlling means can: (1) automatically position the lock assembly at the distal position after the locking arm is rotated from the extended position to the retracted position; (2) automatically position the lock assembly at the distal position when the lock assembly reaches the proximal position; (3) automatically deactivate the positioning means when the lock assembly is immobile; (4) automatically deactivate a synchronous motor after the current or the torque of the motor reaches a predetermined value, and (5) automatically position locking arm tight to wheel for various wheel sizes.
